As the worldwide dietary pattern becomes more westernized, the metabolic syndrome is reaching epidemic proportions. Lifestyle modifications including diet and exercise are recommended as first-line intervention for treating metabolic syndrome. Previously, we reported that specific phytochemical supplementation for 12 weeks (soy protein, phytosterols, rho iso-alpha acids and proanthocyanidins) increased the effectiveness of the modified Mediterranean-style low glycemic load dietary program on variables associated with metabolic syndrome and CVD in subjects with metabolic syndrome and elevated LDL cholesterol. In this study, we propose to conduct a multi-center randomized trial to confirm our previous findings.
